vJAPIARATUS FOR DYEIG WOOL AND THE LIKE.

To all whom. it may concern Be it known that I, ANDREW MURRAY, a subject of the King of Great Britain, resid-V ing at Geelong West., in the State of Victoria, Australia, have invented an Improved `Agipar'atus for Dyeing lW'oolv and the Like,

which the foltowing is a. specification.

This invention consists of an improved apparatus for dyeing wool and particularly topsl of-wool as well as cotton or other material in such a manner that approximately boiling dye liquor is circulated through the material contained in a vat so that a uniform standard of dyeing is insured. -By means of this apparatus it is unnecessary to,stir the material so that it will not be broken, matted, roped or otherwise damaged and moreover it` lessens the labor usually required in known apparatus for dyeing wool and like material.

The accompanying drawings illustrate one suitable form of the apparatus and comprise F gure 1 a vertical section of one embodiment of the invention particularly adapted for dyeing tops, and Fig. 2 a planV of the casina.

'Reerring to these drawings 1 desi ates a .xooden or other casingor vat adapte to contain the dye liquor and 2 a cage having perforated sides and bottom as shown and adapted to contain the 'wool or other material. The bottoinlll 4of the cage is prefreadily connected or fittedto branches 4 leiding from a central dist-ributer 5 connaoted to the delivery pipe 6 of a' ump 7, the suction pipe 8 of which leads rom the bottom of the vat. Y

Above the bottom of thevat beneath the cage a steam coil 9 is rovided for primarily ll boiling the dyeing iquor and forlsubsequently keeping up the temperature. A steam jet- 10 is moreover provided in the de livery pipeG or elsewhere in the feed pipes and is brought into operation when the d veing liquor has reached boiling point. in order v specification uf Letters Patent. Patented Apr. 29, 1913.

Application led J' une 19, 1912. Serial No. 704,578;

to maintain the desired approximately boil.'- ing temperature of the liquor which otherwise naturally loses some degrees of heat during. circulation.

The material, such as tops, is wound around the perforated pipes 3 in the cage and the heated liquor is drawn through the.

suction pipe 8 and delivered through the de` livery pipe 6 and distributed through said perforated pipes and through the material around same after which the liquor percolates through the sides of cage and perforated bottom 11 of the 'cage and is again drawn away by the suction pipe of the pump. By this circulatin process 'the material is continuously-an thorou hl is particularly designed the perforated pipes are formed of readily jointed pieces upon each of which is wound a'ball of tops T, which are separated by perforated distance disks 15 slipped over saidpieces. These disks are placed at proper intervals so that each ball will be operated upon separatelyl thereby insuring a. uniform standard of dyeing. The cage 2 .is closed vnear the top by a plate 17, which is provided with aper-- tures through which the'upper ends of the pipes 3 project said plate resting on the top balls T of material. `The upper ends of th pipes 3 areclosed by caps 16 which mayenimpregnated with the dye liquor'wit'i t e regage the plate 17 and hold the latterf in place@ The delivery pipe "of the pump is .provided with a three way cock 18 which is convnectedwith a discharge pipe 19,',bywhich means the vat may be emptiedi, y 1f 'Lolaimz '.'fi" 1. A dyeing apparatus comprising a vat, a cage mounted therein forming a space be` tween the vat. 'and cage and a chamber bclow the latter, a heating device mounted, in the chamber, a pump, a suction pipe con-- neet-.ing the latter witlithe cha bei', dis' tributing pipes mounted in the atter and connected with the pump, and perforated pipes extending vertically through. the cage adapted'to hold the material to be dyed.

2. A' dyeing apparatus'comprising a vat, a cage mounted therein forming an annular` space between the vat and cage and a chamber between the bottomsv of the cage and vat, a. heatingdevice mounted in the chamber, a suction pipe leading from the chamber, distributing lpipes mounted in the latter, perforated .supportingA pipes connected with the distributing pipes and extending vertically through the cage, and a pump connected with the suction pipe adapted to a heating device mounted in the chamber.

a. suction pipe leading from the chamber, 'distributing p'ipes mounted in the latter. perforated supporting pipes connected with the distributing pipes and extending vertically throngh rthey cage, caps closing the upper ends of the perfrated pipes, and a pump connected with the suction pipe adapted to suck heated fluid from the chamber and force 'said Huid through the distributing pipes and out of the perforated pipes and back to the chamber.

4. Adyeing apparatus comprising a vat, a receptacle removably mounted therein having Va perforated bottom and sides, said receptacle and vat forming an annular space between their sides and a chamber between their bottoms, anfimperforate top for the receptacle, a steam coil mounted in the chamber, a suction pipe leading from the .chamber, distributing pipes mounted in the chamber, perforated pipes detachably connected to the distributingpipes extending vertically through the receptacle, a pump connected with the suction pipe, and a dclivery pipeconnecting the pump with the distributing pipesxwhereby heated liquid may be withdrawn from the chamber and forced through the receptacle back to thel chamber.

5.` A dyeing apparatus comprising a vat, a receptacle removably mounted therein having a perforated bottom and sides, said re- -ceptacle und vat forming an annular space between their sides and a chamber between their bottoms, an imperforate top for the receptacle, a steam coil mounted in the chamber, a suction pipebelow the steam coil leading from the chamber, radially projecting distributing pipes mounted in the chamber, perforated pipes detachably connected to the distributlng pipes extending vertically through the receptacle, caps closing the tops of the perforated pipes, a pump connected with the suction pipe, and a delivery pipe connecting the pump with the their bottoms, an imperforate top for the receptacle, a steam 4coil mounted .in the chamber, a suction pipe below the steam coil leading from the chamber, radially projecting distributing pipes mounted in the chamber, perforated pipes detachably connected to the distributlng pipes extending vertically through the receptacle, caps closing the tops of the perforated pipes, a ump 'connected with the suction pipe, a de ivery pipe connecting the pump with the distributin pipes whereby heated liquid may be with rawn from the chamber and forced through thereceptacle baekto the chamber, and a steam' jet in the delivery pipe,

'7. A dyeing apparatus comprising a vat, a receptacle removably mounted therein having a perforated bottom and sides, said receptacle and vat forming an annular space between their sides and a chamber between their bottoms, an imperforate top for the receptacle, a steam coil mounted in the chamber` a suction pipe below -the steam coil leading from the chamber, radially projecting" distributing pipes mounted in the` chamber, perforated pipes detachably connected to the distributing pipes extending vertically throu h the receptacle, caps closing the tops of t e perforated pipes,a pump connected with the suction pipe, a delivery pipe connecting the pump with the distributing pipes whereby heated liquid may be withdrawn from the chamber and forced through tht` receptacle back to the chamber, a steam jet in Lhe delivery pipe, a discharge pipe in the latter, and a three-way cock 1n said delivery pipe adapted to direct the flow of .liquid alternately through the discharge and delivery pipe.

In testimony whereof I have hereunto set, my hand in presence of two subscribing witnesses.
